After talking to zmedico privately, and raising the issue and
discussing it with people in bug #481578[0], I implemented the
behaviour described in a comment[1] on said bug.

I sent this to zmedico almost two months ago, but it doesn't look like
he's coming back any time soon, so I'm sending it here and ask someone
to review and commit it (a role zmedico has typically played for me,
as well as being my "mentor" and guide and so on and so forth for
Portage hacking).

Remove the --autounmask option from emerge. Please note that removing
the option does not mean that the variable used for keeping track of
autounmasking is not removed from depgraph.py.

I'm with zmedico in comment #11, and *STRONGLY* oppose this change as 
you're proposing.  Current autounmask is **NOT** useless.

FWIW, I have a very specific portage layout and there's no way "dumb 
automation" could put what I'd consider the appropriate write in what I'd 
consider the appropriate file, nor do I want it to try!  (And even if it 
could do it perfectly, I want to /know/ what my config is, and the best 
way for me to /know/ my config is if the only way it changes is if I 
change it myself!)

OTOH, current default autounmask (without write) behavior, having portage 
tell me what (it thinks) I need to unmask and/or what package.use flags 
it thinks I need is fine, and often quite helpful indeed, as long as it's 
not actually trying to actually WRITE it anywhere!

If I read the above correctly, what you're proposing would kill that 
behavior entirely if --ask is used, defaulting to writing (fine if it can 
be turned off), with no way (at least no way with --ask instead of
--pretend) to tell portage to make the suggestion it with --autounmask 
(which is the default now), with absolutely no chance it's going to 
attempt to actually rewrite my config on its own, period.

OTOH, Zac's suggestion, to simply enable autounmask-write by default but 
allow the user to set --autounmask-write=n if they want, would be just 
fine, since I could put that in default options and be done with it.

Tho even that's a sufficiently drastic change from current behavior that 
I'd expect a good changelog entry mentioning it, and preferably a news 
item, as it has the potential to screw up people's configs if they aren't 
paying attention when the default changes.

I don't understand this sentence, but I think you *don't* understand
what I am saying. Please read comment 10[1], in which I present examples.

Enabling --autounmask-write by default is a terrible idea. It will
result in a lot of spam. Furthermore, consider comment 13[2].

I agree that a news item could be useful.

I read comment 10, and am objecting based on it, because there'd be no 
way to do what I'm doing currently and which my workflow depends on, 
which you call irrelevant (below).

1) Because the dependency calculations take time, I normally use --ask so 
I don't have to have portage redo those calculations if I like what its 
telling me it's going to do.

2) Under no circumstances do I want portage rewriting masks, etc, on its 
own, not even with config-protect.

3) Despite that, I find the suggestions it makes saying what it /thinks/ 
it needs unmasked useful -- I just want to write them to the file I want, 
with the comment I want (sometimes with a bit different atom, too), which 
portage wouldn't do.

4) You're saying emerge --ask foo would write the config, and I don't see 
any way to turn that off without also turning off portage's suggestion 
generation as currently controlled by --autounmask (which is on by 
default), or without switching --ask to --pretend.  Your proposal is 
broken behavior as far as I'm concerned, because I find portage's 
suggestions (current autounmask) useful, not the entirely useless you 
seem to think they are without automatically writing them, which I do NOT 
want portage to do under /any/ circumstances.

5) There needs to be a way to get portage's current emerge --ask
--autounmask foo (without --autounmask-write) behavior, because that's 
/exactly/ what I use and find most useful.  But I don't particularly care 
what the default is since I can configure it as needed, as long as this 
current behavior remains possible.

I'd tend to agree, but in that case, why are you wanting to do away with 
the ability to have portage spit out its opinion, without having portage 
actually do the write, while using --ask?

All of this is irrelevant to my patches.

No. Please read comment 10[0].

There is. This doesn't change in my patches. Please read the code or
comment 10[0].

Because it can be done without --ask. See comment 10[0].

Quoting one example from comment 10:

emerge --ask foo
would also do what is currently done by: emerge --ask --autounmask-write 
foo

Which is exactly what I said, and what you're now saying it won't do, 
while pointing at comment 10 which says exactly the opposite.

It's that change in behavior based on comment 10 that I'm most 
protesting, since I depend on being able to tell portage to go ahead with 
the merges if they look good (thus the --ask), but under *NO* 
circumstances do I want it writing its changes to the various use/mask 
files.

The only way you propose to do that in comment 10 is with --pretend, 
which would be a seriously negative change in behavior for my use-case, 
since it would require having portage recalculate the dependencies it's 
just calculated with the --pretend, without it.  --ask currently avoids 
that situation, since when I'm happy with the output, I can simply let it 
go ahead.

You don't understand what this does. Please try it.

It doesn't.

You don't understand how --autounmask and --autounmask-write works, or
I don't understand what you mean. Please try

=www-client/firefox-24.1.1 --autounmask=y --ask
# Assuming you are on a stable system, if not, try another package.

I turn off autounmask because I don't find it useful.  I have found too
many times when it wants me to unmask something that really doesn't need
to be unmasked.

It is not clear to me from the patches if I can still do that.

Paul

I don't understand your predicament. --autounmask per today just
prints out necessary keyword changes. If you run without --autounmask
it doesn't print them. I attached an example.

Someone posted in #gentoo-portage that they had spoken to him, and that
he was just taking a break. (I don't remember who made this post.)

His devaway is «limited availability; please feel free to maintain
"my" packages @ 2013/11/13 12:19Z».
